Yes. I have a Mirage equppied Bianchi and there's nothing sweeter than a hard push on both thumb levers at once to get you from the big ring/biggish cog combo to the middle ring/middle cog combo or the reverse nice hard simultaneous sweep of the front levers to get you into a nice big gear for that long, straight flat.
